C/V Chart and Operating Point
The CPS-EC series provides a perfect current voltage chart. It has no fold
back or other abnormalities. The output voltage can drop down to zero volts
when the power supply is overloaded. The unit delivers a stable and constant
current to the outputs. The device can be used either in the CV or in the CC
mode (automatic switch over). When the output voltage is set to the maximum
demanded value and the current limit reaches its desired margin, the output
voltage drops down and the unit delivers constant current. Similar is when the
upper margin of the voltage allows the current to be dropped by the power
reduction behavior of the CPS-EC series. The C/V setting must meet the

Inrush Current Limiter
The unit is featured with an electronic inrush current limiter (ex. 230Vac = 14,7Arms / 20,7Apeak). The built-in
circuit is a very precise limiter and no simple NTC thermistor solution. The circuit works with an accuracy of
±10%. The accuracy is independent from the ambient temperature and from the number of power-on
sequences. The quickest recommended MCB is B-type 16A (230Vac). The smallest power relay or a contactor
in front of the CPS-EC1500 must cope 20,7A peak current. The inrush duration is 400ms and the overall power
up time of the unit is 500ms. See the below drawings for technical information.
